对象

var person = {};

[object Object]

基本使用

var person = {
  name : ['Bob', 'Smith'],
  // 子命名空间
  name2 : {
      first : 'Bob',
      last : 'Smith'
  },
  age : 32,
  gender : 'male',
  bio : function() {
    alert(this.name[0] ' is ' + this.age );
  }
};

// 使用
person.name[0]
person.name[1]
person.name2.first
person['name2']['first']
person.age
person.bio()

//设置
person.age = 45
person['name2']['last'] = 'Cratchit'

面向对象

例子

function createNewPerson(name) {
  var obj = {};
  obj.name = name;
  obj.greeting = function () {
    alert('Hi! I\'m ' + this.name + '.');
  }
  return obj;
}

// use
var salva = createNewPerson('salva');
salva.name;
salva.greeting();

继承

function Person(first, last, age, gender, interests) {
  this.name = {
    first,
    last
  };
  this.age = age;
  this.gender = gender;
  this.interests = interests;
};

function Teacher(first, last, age, gender, interests, subject) {
  Person.call(this, first, last, age, gender, interests);

  this.subject = subject;
}
